Referring to Fig. l, cylinder 20, fifty-four inches in diameter, hasjust been driven inside cylinder 22 and the driving apparatus is stillin operative position but ready to be withdrawn preparatory to loweringa fifty-two inch cylinder inside cylinder 20, whereupon the drivingapparatus will be adjusted for a cylinder of that diameter and loweredto operative position on the new cylinder.

The driving apparatus comprises a hammer 24 guided for vertical movementbetween I beams 26, tied together at their upper ends byl cross channels28. Cable 30, attached to the top of the hammer by loop 32, serves tomanipulate the hammer and, since the hammer is larger than the spacebetween channels 28, the cable is used also to raise and lower theentire apparatus.

Rivet-ed to the lower ends of guides 26 by means of gusset plates 34 area pair of horizontal channels 36 with their flanges toward each other soas to form a substantially rectangular tubular container or guideway forthe two settable driving beams 38 and 40. Channels 36 are bound togetheron their exteriors by plate 42 across their lower flanges, by plate 44across their upper flanges, and by steel angles 46 across the tops ofthe channels. These angles, with their outstanding flanges removed,extend down the sides of channels 36 underneath gussets 34. To completethe filling between gussets and channels. the triangular plates 48 areprovided.

Within the channels, at top and bottom, are filler plates 50 and 52 soshaped as to form with the webs of the channels a truly rectangularhorizontal supporting guideway for the beams 38 and 40. Y

Above the guide channels and between the lower ends of vertical guides26 is a cushion block 54 of wood or other suitable material, held inposition by channel 56 and angles 58.

Beams 38 and 40 are similar in shape and are mounted for operation onein each end of the above described horizontal guideway between channels36. Each beam is provided with wings 60 and 62, projecting from thesides thereof (Fig. 8) and resting on angle guides 64 and 66 welded tothe webs of channels 36. The beams are therefore slidably supported byguides 64, 66 and by plate 50. The beams are provided with extensions 68and 70 which overlap each other when the beams are set for cylinders ofsmall diameter, and which serve to guide and suppOl the beams in alltheir operative positions, as for instance when fully extended as inFig. 4.

Each beam is provided with a horizontal bore 72 at the open end of whichis a threaded nut 74 (Figs. 8 and 9) held by pins 76, through which arethreaded screws 78 and 80, screw 78 being left threaded and screw 80right threaded. The adjacent ends of the screws are coupled by jawcoupling 82, and the screws are supported for rotation by bearings 84and 86 beside the couplings 82. Fast on screw 78 is a bevel pinion 88 asimilar pinion 90 in mesh with pinion 88 is fast on the inner end ofstud 92 which is supported for rotation in a bushing`94 fast in the webof one channel 36 and reinforcing plate 96 welded thereto and providedon its outer end with a square portion adapted to receive a handle orwrench. It will be appreciated that when stud 92 is turned by the wrenchof the operator, screws 78 and 80 will move beams 38 and 40simultaneously outwardly or inwardly. Scale 98 on the upper flange ofbeam 38 aids the operator in setting the beams at predetermined points.A set screw 99 serves as a stop to limit the outward travel of the beamsto prevent them becoming disengaged from their screws.

The outer ends of the beams are fitted with detachable hardened jawpieces 100 held in place in the beams by washers 102 through which passbolts 104. Thus the jaws may be readily replaced. Each jaw has adownwardly projecting lip 106 which engages the outside of the top ofthe cylinder, while the downwardly projecting surface 108 (Fig. 9) ofthe beam engages the inner surface of the cylinder.

It is to be understood that the invention is not limited to the specificembodiment herein illustrated and described but may be used in otherways without departure from its spirit as defined by the claims whichfollow.

We claiml. In apparatus for driving hollow cylinders, in combination, apair of driving beams, a horizontal guideway for supporting said beamsin alignment with each other, the opposite ends of said beams projectingbeyond said guideway to engage a cylinder, manually operable means forsimultaneously and equally adjusting said beams into and out of saidguideway whereby the apparatus may be adapted for driving cylinders ofdifferent diameters, members carried by the horizontal guideway, and aforce applying means operating within said members for applying adriving force to said guideway and for bodily raising said apparatus.

2. In apparatus for driving hollow cylinders, in combination, aplurality of driving beams having inclined outer ends, jaws in the outerends of said beams overhanging the inclined surface thereof andcooperating with the inclined surface to provide a cylinder wall recess,said beams at their outer ends adapted to have the inclined surfacesengage the inner rim of a cylinder and said jaws adapted to engage theltop of a cylinder and overhang the outer rim of said cylinder wherebylateral displacement of the beams is prevented when driving, togetherwith means for adjusting said beams simultaneously and equally to adaptthe apparatus for driving cylinders oi different diameters.

3. In apparatus `for driving cylinders, a support, driving beamslaterally adjustable in said support for engaging cylinders of varyingdiameters, guiding members carried by the support, a force applyingelement operating within the guiding members to apply a `driving forceto said support, and means for raising the driving beams out of contactwith the cylinder, said means operating through the force applyingelement.

4. In apparatus for driving cylinders,va

support, driving beams laterally adjustable in said support for engagingcylinders of varying diameters, guiding members carried by the support,a force applying element operating within the guiding members to ap-4ply a driving force to said support, means connecting the guidingmembers, and means for operating'the force applying element said forceapplying element coacting with said connecting means to raise thedriving beams out of engagement with the cylinder upon raising the forceapplying element above its normal operating range.

In testimony whereof we hereto alfix our signatures.
